Sinople theme implements defense-in-depth with multiple security layers:

• Content-Security-Policy (CSP) with wasm-unsafe-eval only (no unsafe-inline, no unsafe-eval)
• Cross-Origin-Embedder-Policy (COEP): require-corp
• Cross-Origin-Opener-Policy (COOP): same-origin
• Cross-Origin-Resource-Policy (CORP): same-origin
• Strict-Transport-Security (HSTS) with preload
• Permissions-Policy (all dangerous features disabled)

• Chainguard Wolfi base images (supply chain verified)
• Seccomp profile limiting syscalls to necessary minimum
• AppArmor/SELinux profiles for mandatory access control
• Capability dropping: ALL capabilities dropped, only essential added
• Read-only filesystem with tmpfs for necessary writes
• Non-root user (UID 10001)
• Network isolation: Internal services on isolated bridge network

• All user input sanitized via WordPress escaping functions
• File upload validation with MIME type checking
• SVG sanitization to prevent XSS
• SQL injection prevention via prepared statements (WordPress WPDB)
• Command injection prevention (no shell execution of user input)

• Partitioned cookies (CHIPS) for cross-site tracking prevention
• IP anonymization in logs and comments
• Do Not Track (DNT) header respect
• No external resources without explicit user consent
• ECH (Encrypted Client Hello) readiness

• ✅ A01:2021 Broken Access Control - WordPress capability system + RBAC
• ✅ A02:2021 Cryptographic Failures - TLS 1.3, modern ciphers, HSTS
• ✅ A03:2021 Injection - Prepared statements, input sanitization, CSP
• ✅ A04:2021 Insecure Design - Security-by-default architecture
• ✅ A05:2021 Security Misconfiguration - Hardened defaults, header automation
• ✅ A06:2021 Vulnerable Components - Chainguard Wolfi (minimal, patched)
• ✅ A07:2021 Authentication Failures - WordPress authentication + rate limiting
• ✅ A08:2021 Software/Data Integrity - Subresource Integrity (SRI), signed containers
• ✅ A09:2021 Logging Failures - Structured logging, security event monitoring
• ✅ A10:2021 SSRF - No outbound requests without validation, internal network isolation

1. Use HTTPS only with valid SSL/TLS certificates (Let's Encrypt recommended)
2. Enable all security headers via nginx/Apache configuration
3. Set strong database passwords (minimum 32 characters, randomly generated)
4. Enable fail2ban for brute force protection
5. Configure firewall to allow only ports 80, 443, 22
6. Regular updates: Keep WordPress core, plugins, and theme updated
7. Backup regularly: Automated daily backups with off-site storage
8. Monitor logs: Set up log monitoring and alerting
9. Scan containers: podman scan sinople-theme:latest before deployment
10. Review CSP: Adjust Content-Security-Policy for your specific needs

1. Never commit secrets to version control
2. Use .env files for sensitive configuration (add to .gitignore)
3. Enable WordPress debug mode only in development
4. Use development docker-compose (not production config)
5. Scan dependencies: npm audit, cargo audit, composer audit

• User data: Posts, comments, user accounts, personal information
• Authentication: Session tokens, cookies, API keys
• Content: Published articles, images, custom taxonomies
• Configuration: Database credentials, API secrets

• XSS: Mitigated by CSP, output escaping, input sanitization
• SQL Injection: Mitigated by prepared statements, parameterized queries
• CSRF: Mitigated by WordPress nonces, SameSite cookies
• RCE: Mitigated by file upload validation, no eval(), seccomp
• SSRF: Mitigated by input validation, network isolation
• DoS: Mitigated by rate limiting, resource limits, fail2ban
• Supply Chain: Mitigated by Chainguard Wolfi, SRI, dependency scanning

• WordPress core is secure: We rely on WordPress security team
• Server is hardened: Firewall, SELinux/AppArmor enabled
• TLS terminates at reverse proxy: Nginx handles SSL/TLS
• Database is isolated: Not exposed to internet

• Automated security scanning in CI/CD
• Dependency vulnerability monitoring (Dependabot/Renovate)
• SBOM (Software Bill of Materials) generation
• Signed containers (cosign/sigstore)

• FIDO2/WebAuthn support for 2FA
• Audit logging with tamper-evident storage
• Security dashboard in WordPress admin
• Automated penetration testing

• SOC 2 Type II compliance documentation
• Bug bounty program
• Third-party security audit
